Here's an amusing tale (sort of) - I've been desperately trying to understand the colour schemes for Me109s, in particular the standard grey pattern called RML-74/75/76, and have searched high and low for reference photos.
Well, I just happened to be trawling through my own Flickr gallery today and came across this snapshot that I took while I was visiting the fantastic Yorkshire Air Museum...
It's a Me 109 G-6, exactly the type that I'm interested in at the moment. Who'd have thought that I would find an example more or less on my own doorstep, let alone a photo I actually took of it myself!
Incidentally, I should add that the YAM is a 'must see' attraction if you find yourself in Yorkshire. I's very well laid out and has some unique 'museums with a museum', like the air gunners museum and the beautiful remembrance memorials (chapel and garden).
